I wonder if this is related to why it's easy to learn touch typing while saying the keys out loud.
I didn't know it was. Can you direct me to some research there; I'm curious about that now.
Just speaking of my own experience.

#42Earlier quoted context omitted.
(8) Animals communicate mainly via sound. Most don't even have hands.
(9) Talking in a group. It seems to me with gestures you can understand only one person at a time. Though maybe deaf people who use sign language have a good way to handle this.
This is a potential strength of hand signals, too, though. As the article mentions, voice is more of a broadcast medium, while hand signals would be a more discreet multicast kind of thing.
